Reasons for ineffective brakes: 1. Excessive free travel of the brake pedal; 2. Insufficient or no oil in the brake master cylinder reservoir; 3. Air entering the brake lines or vaporization of brake fluid causing air resistance; 4. Aging or wear of the master cylinder and wheel cylinder cups leading to poor sealing; 5. Loose or detached vacuum pipe connections of the vacuum booster or power booster; 6. Diaphragm rupture or poor sealing of the sealing ring. In vehicles, braking mainly refers to pressing the brake pedal, which relies on the friction between the brake pads and brake discs to generate resistance, thereby slowing down or stopping the vehicle. Whether it's a manual transmission or an automatic transmission model, the brake pedal of a car is controlled by the right foot.

What is the actual fuel consumption of the Haval H9?

Haval H9's fuel consumption is 9.9 liters per 100 kilometers. The actual fuel consumption is closely related to the vehicle's condition and road conditions, and is not an absolute value. The reasons for increased fuel consumption and the methods for calculating fuel consumption are as follows: Reasons for increased fuel consumption: Use of inappropriate fuel; aging of engine spark plugs and excessive carbon deposits directly affecting ignition efficiency; clogged fuel system, such as a dirty fuel filter. Methods for calculating vehicle fuel consumption: The first method involves resetting the odometer data through the vehicle's dashboard. The onboard computer automatically calculates the fuel consumption based on the recorded mileage and fuel consumption data. The second method involves recording the mileage after a single refueling and then calculating the vehicle's fuel consumption. The fuel consumption obtained by both methods represents the average fuel consumption of the vehicle.

What is the real reputation of the Beijing BJ40 Plus?

Beijing BJ40 is a car that deserves recognition in terms of overall performance. Whether it's space comfort or power, it performs well. Here are the specific details: 1. Space: The front row space is sufficient, while the rear row space is not very spacious and can feel a bit cramped compared to sedans. However, for an SUV, the rear space is acceptable. There is ample headroom, but be aware that the lack of a roll cage may lead to hitting your head when moving around. In terms of storage space, the center armrest storage is sufficient, but the rear row has almost no storage space except for a cup holder on the armrest. The trunk volume is large and square-shaped. When the rear seats are folded down and flipped forward, the entire area behind the front seats becomes trunk space. 2. Power: The initial acceleration is strong, and the car picks up speed quickly. There is some delay in engine downshifting during rapid acceleration, but this can be significantly reduced by switching to Sport (S) mode or using manual shifting. Overall, the power performance is good, allowing for easy overtaking.

What's the Difference Between Street Bikes and Sports Bikes?

Regarding sports bikes, we know that their riding posture is more aggressive due to lower handlebars, higher footpegs, and a taller seat height. In contrast, street bikes offer an upright and more relaxed riding position, making them more suitable for the general public. The specific differences are as follows: 1. Sports bikes generally refer to race-replica models: Sports bikes, often called race-replica or sport-type motorcycles, prioritize high-speed performance above all else, sacrificing other elements. Their full-body fairings cover over 40% of the bike, with an aggressive riding posture and a lowered center of gravity to facilitate cornering and counteracting turbulence and wind resistance at high speeds. They typically feature engines with more than two cylinders—four-cylinder 600cc models are considered entry-level by professional riders—with top speeds generally exceeding 220 km/h and a total weight over 180 kg. These bikes are better suited for track use rather than urban riding. 2. Street bikes are generally not overly heavy: Street bikes emphasize riding comfort, ease of operation, and flexible control while maintaining high performance. They often showcase exposed metal components as a selling point, with minimal aerodynamic features. Classic examples include cruiser-style bikes and streetfighters. Notable Chinese models include the Phantom, Benelli TNT 300, KPR, and various cruiser-style bikes like the Suzuki King. 3. Frame: Road sports bikes and street bikes differ significantly in frame construction. Sports bikes typically use aluminum alloy beams, while street bikes often rely on welded steel tube "cradle" frames. Their engines also differ—road sports bikes feature inline-four engines with a steeper tilt angle compared to street bikes. Additionally, their transmission gear ratios are optimized for higher speeds, resulting in weaker low-speed acceleration but superior high-speed performance. 4. Riding posture: Street bikes offer a more comfortable riding position with a higher center of gravity, allowing for a relaxed posture that reduces fatigue during medium to long-distance rides. In contrast, road sports bikes require riders to support significant upper body weight, making rides over 80–100 km exhausting. If carrying a passenger on a high-low seat setup, the combined weight places immense strain on the rider's arms—often causing severe fatigue within 50 km. Additionally, hard braking could potentially throw the passenger forward in most cases.

What grade of gasoline should the Magotan use?

Magotan should use 95-octane gasoline, as this fuel grade is recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, you can also find it marked on the fuel tank cap. Generally, the fuel grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, those between 10.0-11.5 should use 95-octane gasoline, and those with higher compression ratios should use 98-octane gasoline. However, with the application of new technologies, the compression ratio alone cannot determine the fuel grade—engines with high compression ratios can also be tuned to use lower-octane gasoline. Other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If the Magotan occasionally uses the wrong gasoline grade, simply switch back to the correct grade after the tank is empty. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended for low-octane gasoline, using a higher-octane grade will not cause damage, but the increased octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles recommended for high-octane gasoline, using a lower-octane grade can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance builds up during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without obvious engine damage, but severe knocking indicates serious engine issues, affecting driving stability and causing abnormal wear on pistons and cylinders—or even cylinder scoring in extreme cases.

Parking Without Turning Off the Engine: P or N Gear?

Parking without turning off the engine should be done in P gear. Below are detailed introductions to the automatic transmission gears: R Gear (Reverse Gear): When this gear is engaged, the hydraulic system's reverse oil circuit is activated, causing the drive wheels to rotate in reverse for backward movement. Do not forcibly shift to 'R' gear when the vehicle is not completely stopped, as this may damage the transmission. N Gear (Neutral Gear): When neutral gear is engaged, the planetary gear system idles and cannot output power. D Gear (Drive Gear): When the gear shift lever is in this position, the hydraulic control system automatically connects the corresponding forward gear oil circuit based on throttle opening and vehicle speed signals. It can automatically shift up or down according to driving speed, achieving automatic transmission functionality. P Gear (Parking Gear): This gear uses a mechanical device to lock the rotating parts of the car's tires, preventing the vehicle from moving. L Gear (Digital Limited Gear): The transmission can only switch between limited gears in this mode. '1' or 'L' represents the transmission's lowest gear, typically used only when extremely powerful torque is required, such as climbing steep slopes or towing heavy vehicles.
